Definitions

  • the present invention relates to a panel for a facade with an extruded or pressed molding of a mixture of natural materials and a polymer material having a visible outer side, and a method for producing a panel for a facade.
  • the DE 10 2008 056 425 discloses a facade with several panel-shaped facade elements of extruded panels.
  • the panels are fixed by fasteners on a building wall and have a flat outside.
  • the panels are designed monochrome, and thus the visible surface can be perceived as monotonous.
  • the façade can only be adapted to individual wishes to a limited extent.
  • the panel according to the invention comprises an extruded or pressed molding of a mixture of natural materials and a polymer material.
  • the molded body is extremely weather-resistant, because despite the use of natural substances in the molded body, these are incorporated into a polymer matrix and are therefore largely unsusceptible to moisture absorption. Weathering tests with the molded body have shown that it has a high dimensional accuracy even with permanent irrigation and only a slight swelling of the material occurs.
  • the invention provides that a visible outside of the extruded molded body is printed with a decorative coating. By printing the outside, the panel can be designed individually for the purpose, in particular one or more color printed images can be provided, which can be designed according to the wishes of the builder.
  • the decorative coating is formed UV-resistant.
  • both the coating and the molded body can be used over a long period of time with high color fastness.
  • the decorative coating can be monochrome or multi-colored, in particular multi-color printing a decorative image of a wooden surface or tile surface, but also a photo or other decorative element can be printed on one or more panels.
  • the decorative image can also be divided into individual sections, which are then printed on the individual panels to generate a large decorative image on the facade through the individual panels.
  • the decorative coating has a plurality of layers and may have a pre-coating, for example a primer, and / or a sealing layer. Thereby, a high adhesiveness of the decorative coating to the molded article can be obtained.
  • the proportion of natural substances in the molding is preferably in a range between 50% and 85%, in particular 60% to 80%.
  • the natural substances can be formed by natural fibers of wood, wood materials, rice husks, bamboo or other lignocellulose-containing materials.
  • Polypropylene, polyethylene and mixtures of different polymer materials are particularly suitable as polymer materials.
  • a facade is formed on an outer side of a building by a plurality of panels.
  • the individual panels are fixed to the outside of the building via a mounting system and can improve not only the visual design but also the thermal insulation.
  • the panels may be formed with hollow chambers which are open or filled with an insulating material.
  • the panels can be used instead of on a facade for fences, wall elements, privacy elements or floorboards, especially in outdoor areas.
  • a shaped body made of a mixture of natural materials and a polymer material is extruded or pressed.
  • This shaped body is then printed on a visible outer side for producing a decorative coating, so that the visible outer side can be adapted individually for the respective application.
  • the effective production by extrusion or compression can be used to provide a weather-resistant material with good thermal insulation for the production of a panel, which is then optically refined by the subsequent printing.
  • a surface of the extruded or pressed molding is roughened prior to printing.
  • the roughening can be done by brushing or grinding, with a certain surface roughness is introduced into the smooth-walled extruded surface of the molding.
  • a primer can be applied to a surface of the extruded or pressed molded body, which is then printed.
  • the primer can serve as a bonding agent between the extruded or pressed molding and the decorative image and, on the other hand, a very smooth surface can be obtained by the primer.
  • the printed decorative image can be coated with a UV-resistant sealing varnish.
  • the UV-resistant sealing lacquer can be applied either with a uniform layer thickness or with a different layer thickness, which is adapted to the structure of the decorative image, for example. As a result, the appearance of the decorative image with the UV-resistant sealing lacquer can be further improved by the surface structure is adapted to the decorative image.
  • the extruded moldings may have hollow chambers, which are filled with an insulating material, for example.
  • the printing of the moldings can be done by one or more applicator rollers.
  • the printing of the panels can also be done in digital printing, wherein preferably a multi-color print is used, which can be adapted to different decor images in the short term.
  • a panel 1 according to the invention comprises an extruded or pressed molding 2, which is made from a mixture of natural fibers and a polymer material.
  • the proportion of natural fibers for example of wood, rice husks, bamboo or other natural substances, is in a range between 50% to 80%, in particular 60% to 75%.
  • the molded body 2 has a plurality of hollow chambers 3, which may be filled with insulating material if necessary, in order to improve the thermal insulation.
  • At opposite longitudinal edges of the molded body 2 is equipped with a groove 4 and a spring 5, so that the moldings 2 for the production of a facade, a fence or other structure for outdoor use can be easily mounted.
  • Other mechanical connection systems for mounting the molded body 2 can be used.
  • the molded body 2 has a visible outside, which is provided with a decorative coating 6.
  • the decorative coating 6 may be a or more layers and comprises at least one printed image which was subsequently applied to the extruded shaped body 2.
  • the extruded moldings 2 can be cut to the desired length after printing or after extrusion, to be then mounted in a large length of, for example, 3 m to 6 m to a building.
  • the surface of the extruded shaped body 2 can be roughened, for example by brushing, sandblasting or grinding elements, which produce a certain surface roughness, to which then either a pre-coating by a primer or directly the printed image is applied.
  • the printed image can then be protected by a sealing lacquer which is UV-resistant and transparent or translucent.
  • decor images own one or more color printed images that represent, for example, a wood grain or a tile structure or form sections of a photo, which is then displayed on a large scale facade.
  • a panel can then be a small section of a larger decor image.
  • the panels 1 thus produced are particularly suitable for exterior applications on facades, but can also be used as fences, wall panels, floorboards or other structures in the outdoor area.
  • a shaped body is produced from a mixture of natural substances and a polymer material, for example by extrusion or compression in a mold.
  • the shaped body can then be roughened on an outer side, in particular by brushing or grinding.
  • the smooth-walled extruded surface can also be coated untreated.
  • a visible outside of the extruded shaped article is printed to produce a decorative coating.
  • Printing can be done by one or more applicator rollers or by digital printing.
  • the printed surface can optionally be subsequently protected with a UV-resistant coating in the form of a sealing varnish.
